For school program auto orders:

• Don't worry about manually canceling these
• If you drop a course or requirements change, items cancel automatically

For out-of-pocket orders:

• Go to your Student Dashboard on your school's eCampus site
• Click the My Orders tab
• Select the order number containing the book you want to cancel
• You can only cancel orders that haven't been fulfilled yet

If the option is still available you will see it at the bottom of the order item lists.

Once you select the button a new screen will appear for you to fill in your information and check the books you want to cancel.
